Synthesis, Structure, and Reactivity of a Gallylene Derivative Bearing a Phenalenyl-Based Ligand.

Phenalenyl-based N,N-bidentate ligand-stabilized monovalent gallium(I) complex was synthesized and characterized by NMR spectroscopies, single-crystal X-ray diffraction, and theoretical calculations. In solution, complex has a high thermal stability at 80 °C, with an absorption maximum at 505 nm. Complex promotes the oxidative addition of I-I, Si-Cl, C-I, and S-S bonds and oxidative cyclization with various π components. Complex can also coordinate to a tungsten complex to form a Ga-W bond.
